FTP Server software for Windows

Over the course of several years, I have used numerous FTP Server applications, so I thought I would list them out here:

1. Serv-U FTP Server: http://www.serv-u.com/ftp-server
2. BulletProof FTP Server: http://www.bpftpserver.com/
3. WS_FTP Server: http://www.ipswitchft.com/ws-ftp-server
4. Globalscape EFT Server: https://www.globalscape.com/managed-file-transfer
5. FileZilla FTP Server: https://filezilla-project.org/download.php?type=server

Out of all of these FTP Server solutions, I definitely prefer Globalscape EFT Server for the greatest set of functionality including a very good API that can be used for automation.  Of course, Globalscape EFT Server is also one of the priciest solutions out there as well!

As a second choice, I choose WS_FTP Server, though, it lacks some of the ease-of-use features found in Globalscape EFT Server.

Lastly, of the solutions listed here, only FileZilla FTP Server is a free FTP software solution.
